I downloaded utorrent through the expansion Wrath of the Lich King, but when I run it as an administrator and start the wow my mind tells me starting update, restarts and download wow patch 3.3 to 4.0.0 patch - x na and no nothing happens , stays at 0 bytes and then tells me that the tracker does not respond .
What I can do?

I have windows 8.1 pro
cpu fx 8350
amd r9 280x
